.To all 'wh'mnt may eonccrmv `Beit known that I, 4EMIL GaUwE, ofHoboken, in the county. ot' Hudson and State-'ofl .New Jersey, haveinvented a1 new and Im' proved Metallic Building and method ofconetructing'the same, of which tbe'following is a specification: Thisinvention has for its object to produce ahollowmetallic franielwork forhouses and ,other buildings, in :such condition that the me maybereadily and conveniently itted to its place .in the' structure; and theinvention consists in the new combinationof cast )donkey'metal4 glbes,andusupporting-.pieces hereinafter more Vfully described'.

lathe, accompanying drawing, Figurel -1 represente a faee'vewof tbeframe of a. building constructed according to my. invention'. lli'g. is'a top view of the same,and Fig. 3 a

section' on the line c c, Fig. 1. "f fSiinilar letters of referenceindicate corrers ding parte in all.y the figures. i. l'.Asallteadystated', ,the frame of this building is to he mainly' composed ofmetallic tub- ',ing and `I- propose to-make'each post, beam, `and-supporting part in factof the main frame of two or more parallel tubes,A B; and to conneetl these two or more tubes by cast blocks orbraces G,and to form .on several of these .east vblocks tubular sockets D forreceiving crose-tubes E, by which the several beams, and, if desired,also the posts ofthe Vframe ot' fthe structure, may be connected.- Inorder to facilitate the putting together of a structure thus h-made,vandto avoid confusion and delay,v lin t e's'etting'up'of the same, I castthe four, '.ve,mo're orless, connecti'ng'blocks C C, that .are to be putonto each lengthof sectionotpar' v allel tubes A and B,`on these two ormore tubes. by'putting there two or more tubes in proper molds, formingthe cast blocks in which recesses are made forV j.

C C C. each of said blocks having, where necessary, especially on -theroof part, a transverse socket, D, for receivng the cross-'tubing E.These transverse sockets are not requisite on all parts oi' thebuilding`tbr instance, along the uprights, as shown in Fig. 1, whereinstead, thevblocks C C have flanges formed on them for receivingmetallic flat beams F F. The piece of tubing A Beast with'these four,more o'r less, blocks G C will then -constitute a compactandunfchangeable beam for the structure, and can be joined to the otherbeams by right and left nu-ts a a or otherwise, as may be desired, sothat thus the several parts or beams can be readily joined together whenthey have been transported to the place where the structure is to be putup.. post-tubes to the roof-tubes, as in Fig. 1, are also cast withtheir short pipes A Bc for connection with the roof and upright tubes,as

- shown.

The complete building may be furthermore strengthened by Awrought ironor other braces Gr Gr in any suitable way, a part of this invention. Thebuildings to be put up on this plan are chiefly to be sent from thiscountry to, and used in, South America, and where skillful labor isdifficult to obtain, and where, in consequence, it is, desirable toobtain the parts of a structure to be put up inas complete a form as itis possible to ship them.

I claim as my invention- The combination ofthe tubes A 13",l with theconnecting-blocks C G, which have projecting flanges formed on them forreceiving and supporting the connecting-beams F F, substantially asherein shown and described.
